1 Scheugenpflug AG Metering and Dispensing Technology Metering and Dispensing Systems 04 l 13 Metering and dispensing Systems The quality, reliability and consistency of metering and dispensing processes can determine whether a manufactured part is fully functional and whether entire production lines are economically efficient. Exact Metering The tiniest variations in the dispensing process and a slightly inhomogeneous dispensing medium can result in a reduced functionality of your manufactured component. Therefore, it is imperative to keep metering parameters at a specified level and make sure that dispensing remains constant in the production process. Process Reliability Irregularities or interruptions in the dispensing process greatly influence the economic efficiency of your entire production line. The traditionally simple yet rugged build of our machinery combined with technologically advanced elements are the foundation for a reliable dispensing solution with enough room for customisation. Perfectly constant metering quantities, a consistently sustained mixing ratio, reliable airtight machine parts and high availability: These are the major characteristics of Scheugenpflug metering and dispensing technology. They are the result of over 20 years' experience in the dispensing of resins and adhesives.

3 Process Reliability Rugged mechanical construction in a modular design Metering accuracy is independent of temperature, pressure and resin viscosity Exact metering and defined reaction time through separate metering and mixing PRECISION Stable mechanical setting of the dispensing volumes and of mixing ratios determined by the size and volume of the metering cylinders Volumetric Piston Dispenser Dos P Consistently homogeneous mixing obtained by simultaneous discharge of the metering cylinders Anti-Wear Technology Rinsing of seal and cylinder inside wall with every stroke of the piston Ongoing removal of abrasive product residues Function principle of material flow in the piston dispenser two components, 1 nozzle Piston dispenser Dos P two components, 1 nozzle

4 1C 2C Abrasive Highly viscous Atmosphere Vacuum Volumetric Piston Dispenser Dos P High-Precision Dispenser With Reliably Constant Mixing Ratio for Ultimate Process Reliability. The piston dispenser Dos P is a volumetric dispensing system designed to work with one or two component dispensing materials. Depending on the desired dispensing volumes and mixing ratios, metering cylinders with the exact sizes and volumes are available. When two component materials are used, the mixing ratio is kept constant by emptying both cylinders absolutely simultaneously into the mixing tube. As a result, reaction time, or pot life, starts at this very moment. The two components are thoroughly mixed inside of the static mixing tube. The dispensing medium available at the outlet is always perfectly homogeneous. The seal and the cylinder inside walls are cleaned with a rinsing liquid each time the piston strikes, which removes aggressive product residues. This effectively minimises soiling and wear and tear of machine parts. At the same time, the adverse effects of atmospheric moisture are kept at bay. Used for Materials: One and two component Liquid to highly viscous Non-abrasive to highly abrasive Non-filled to highly filled Also suitable for materials sensitive to moisture. Usage: Potting, filling, applying, sealing, bonding, fastening, coating. Protection against moisture, dust, mechanical stress, heat management in the production of electrical or electronic components, solar/photovoltaics, medical engineering, etc. Lifting mechanism with stepper motor and linear guide Machine parts in contact with dispensing material: resin and hardener cylinders, valves, etc. Piston monitoring Inspection glass to check the rinsing liquid level Optional: Valve monitoring Mixing tube heating Dispenser heating Multiple dispensing Multiple piston metering system Multiple functionally interconnected single dispensers Each single dispenser is equipped with separate inlet-/outlet valves and monitoring sensors One common ejector facility guarantees perfectly simultaneous operation Perfectly accurate dispensing, long service life regardless of how many single outlets are used Product variant: Piston dispenser for vacuum dispensing two components, 8 nozzles Data sheet on request.

5 CONTINUOUS DISPENSING The two cylinder pairs are filled and discharged alternatively to ensure uninterrupted production PRECISION Stable mechanical setting of the dispensing volumes and of mixing ratios determined by the size and volume of the metering cylinders Consistently homogeneous mixing obtained by simultaneous discharge of the metering cylinders ALTERNATING Piston Dispenser Dos p-a Piston Metering System for Continuous Dispensing of Large Quantities. By working alternatingly, the two cylinder pairs allow continuous dispensing. One cylinder pair is loaded while the other is discharged. This allows the output of large quantities of dispensing material in very short times. Used for Materials: One and two component Highly viscous but self-levelling Non-abrasive to highly abrasive Non-filled to highly filled Usage: Filling Application of material bands (continuous dispensing) Pneumatic control of inlet and outlet valve opening Piston rod monitoring: monitoring sensor for cylinder filling Mixing tube stabilised with aluminium sleeve Optional: Valve monitoring Mixing tube heating Dispenser heating Alternating piston dispenser Dos P-A two components, 1 nozzle Data sheet on request.

For very small and micro quantities there is the piston metering system Dos PM. It works with highest precision and accuracy and also handles variable metering quantities and speeds. Used for Materials: One component Liquid to highly viscous Non-abrasive to highly abrasive Non-filled to highly filled Usage: Dispensing quantity: to 0.04 ml Application of dots and beads, filling, dam&fill, encapsulation of chips on a lead frame 12-nozzle or 16-nozzle dispenser Piston dispenser Dos PM one component, 16 nozzles Data sheet on request.

7 Continuous Dispensing of Large Quantities FAST & Exact Lightweight and variable geometry High workpiece throughput Straight lines applied with high precision Ultimate Movability The gear pump dispenser has a highly flexible movement range Gear Pump Dispenser Dos GP Using a swivel needle it is possible to trace steeply inclined contours Possible contours supported Gear pump dispenser Dos GP one component, 1 nozzle

8 1C 2C Abrasive Highly viscous Atmosphere Vacuum Gear Pump Dispenser Dos GP Rugged High-Precision Metering Pump for Applying Dispensing Materials in Continuous Flow. Ideal for Processing Variable Quantities at High Flow Rates With Great Accuracy. The gear pumps operate on the principle of rotating volumetric displacement. The geometry of the gear and the number of cogs determine the metering output. The rotating speed of the gears precisely controls the metering output. This renders the dispensing process absolutely continuous and constant. Used for Materials: One component Highly viscous Non-abrasive Non-filled Also suitable for materials sensitive to moisture. Usage: Application of one component sealing beads and other dispensing media onto workpieces for sealing and bonding. Stepper or servo motor Rinsing liquid container with inspection glass Pressure monitoring inlet pressure Pressure relief Optional: Free choice between stepping motor or servo motor drive for optimal suitability in all types of production lines Quick changing of the motor for easy switchover to different dispensers when several are used in turn Swivel needle Inlet Outlet Function principle of gear pump dispenser Data sheet on request.

10 1C 2C Abrasive Highly viscous Atmosphere Vacuum Dispensers for Small and Micro Quantities Dos Jet Dos JetPMU High-Precision Metering Systems for Dispensing of Smallest and Micro Quantities. For smallest quantities in the nanolitre range, the dispensing systems Dos JetPMU and Dos Jet offer extremely high dispensing precision and speed. Opening and closing of the valves is controlled electronically or pneumatically in the two systems. To keep change-over times as short as possible, a plug&play principle is applied. The use of cartridges and simple threaded connections keeps reloading of the dispensing material fast and clean.
